Remove Nth Node From End | Leetcode 19 | Two-Pointer & Two-Pass | Python DSA Telugu | srkcodes
3Welcome to srkcodes, your go-to channel for Telugu coding tutorials, Leetcode solutions, and Python programming for interviews! Today, we tackle Leetcode 19: Remove Nth Node from End of List, an important DSA interview question frequently asked in tech job interviews.
🔍 What You’ll Learn?
✅ Problem Explanation: What is the Nth Node from End of a Linked List, and how do we remove it?
✅ Brute Force (Two-Pass Approach): First, find the length of the Linked List, then remove the node.
✅ Optimal (One-Pass, Two-Pointer Approach): Use a fast and slow pointer to remove the node efficiently.
✅ Python Implementation: A step-by-step walkthrough of both solutions with a detailed time complexity analysis.
✅ Linked List Concept Review: Understand how linked lists work and their importance in DSA interview questions.
This video is part of our DSA in Telugu series, helping you master Python programming for interviews and build strong problem-solving skills.
